Upgrade To Windows 7 Might Take 20+ Hours (Worst Case)

Isn’t it frustrating to
reinstall all your favorite and perfectly working applications after upgrading
or installing an OS on your PC?

Reports confirm that
it took more than 20 hrs to upgrade Windows 7 on a machine of 650 GB data and 40
applications in a mid end hardware configuration and in case of high end
hardware it takes around 10 hours. However, you can have a clean install with
no application in 30 minutes in a high end hardware and 50 minutes in case of
low end hardware (further analysis here). So, if you
really want to install Window 7 quick and fast, first you need to uninstall all
your applications and store it in some place, then install Windows 7 and
then probably you can go about reinstalling all your applications one
by one. That looks like a tedious job.

More than one and half year
has passed and after all the regression testing this is something that comes
out on the up gradation of windows 7 from vista SP1 on a high end hardware
configuration.

In Windows Digital Lifestyle
Consortium in Japan last year Gates talked about the performance
of Windows 7 and suggested that it will take less memory and will be more
efficient. More than one and half year has passed and after all the
regression testing this is something that comes out on the up gradation of windows 7 on a high end
hardware configuration.

Just think about the low end
hardware user, how much time will it take to install windows 7 in their system?
My wild guess says around 2 days (just kidding). Microsoft has already
confused users by giving phantom promises on the efficiency and performance of Vista over XP in past. Just more
than a month left before the official release of Windows 7 on October 22nd.
Lets hope it doesn’t disappoints us again like Vista.
